TRANSCRIPTDevelopers of AI Methods Win Nobel Prize in PhysicsTwo early developers of artificial intelligence (AI) have won this year’s Nobel Prize in Physics.American John Hopfield is with Princeton University in New Jersey. Geoffrey Hinton is a citizen of Canada and Britain who works at the University of Toronto.The Royal Swedish Academy of Sciences honored them for helping “to develop methods that are the foundation of today’s powerful machine learning.”The 76-year-old Hinton is known as the Godfather of artificial intelligence for his part in developing machine learning. However, he also has warned that AI has created threats to humanity.Godfather n. 教父，创始人Ellen Moons is a member of the Nobel committee at the Royal Swedish Academy of Sciences. Moons said the two scientists “used fundamental concepts from statistical physics to design artificial neural networks that function as associative memories and find patterns in large data sets.”neural adj. 神经的，神经网络的Moons added that their research has been used to make progress in physics but has also become part of people’s daily lives. Technologies like facial recognition and language translation are used every day.(Q1) Hinton predicted that AI would have a “huge influence” on civilization and will bring improvements to productivity and health care. He told reporters and Royal Academy officials that, “It would be comparable to the Industrial Revolution.”The Industrial Revolution was a period of intensive development of machines and manufacturing that started more than 250 years ago in Britain.Hinton said, “Instead of exceeding people in physical strength, it’s going to exceed people in intellectual ability.” (Q2) But Hinton also expressed concern about the possible bad results of AI, especially noting, in his words, “the threat of these things getting out of control.”The Nobel committee also recognized the possible damage the discoveries that it was honoring could cause. (Q3) Moons said AI’s “development has also raised concerns about our future. Collectively, humans carry the responsibility for using this new technology in a safe and ethical way for the greatest benefit of humankind.”ethical adj. 伦理的，道德的What they didIn the 1980s, Hinton helped to develop a method known as backpropagation, which is used to “train” computers to learn.Later, he headed a team at the University of Toronto that won the ImageNet computer competition in 2012 for designing a “neural network.”Hinton and AI scientists Yoshua Bengio and Yann LeCun won the Turing Award in 2019. It is the top award in computer science. That year, Hinton told the Associated Press about the reaction he and his fellow researchers received over their work.They thought “we were very misguided and what we were doing was a very surprising thing for apparently intelligent people to waste their time on. My message to young researchers is, don’t be put off if everyone tells you what you are doing is silly."be put off 失去兴趣或感到厌烦Hopfield is now 91 years old. (Q4) The Nobel committee said he “invented a network that uses a method for saving and recreating patterns.”Hinton used Hopfield’s network to create a new network using a different method known as the Boltzmann machine. The committee said this “machine” can learn to recognize elements in a particular kind of data.“What fascinates me most is still this question of how mind comes from machine,” Hopfield said in a video posted online by the Franklin Institute after it awarded him a physics prize in 2019.The Nobel Prize in Physics is valued at $1 million. Swedish inventor Alfred Nobel created the prizes to honor discoveries that help humanity. The first prizes were awarded in 1901.On Wednesday, the prize in chemistry will be announced; on Thursday, the prize for literature; and Friday, the peace prize. The Nobel for economics will be announced on Monday.The winners receive their prizes in ceremonies held on December 10.Part III. KEYQ1.

Discovering trends in large datasets.D. Replacing humans in various fields.Part II. TRANSCRIPTImportant Terms and Ideas for Describing Artificial IntelligenceThere are several terms experts use to describe computer systems in the field of artificial intelligence. Recently, the French News Agency (AFP) defined some of the common terms and ideas used in that field. Here is a version for English learners:intelligence n. 智力，智能Artificial intelligence The first term is “artificial intelligence.” When asked what artificial intelligence is, the AI-powered ChatGPT system says that the term means “the simulation of human intelligence in machines that are programmed to think, learn and make decisions”. (Q1) AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. AI involves using ideas from many fields including computing, mathematics, languages, psychology, and others. Currently, the technology is being used heavily for investigating health issues, translating human languages, and predicting problems in machine tools and self-driving cars. But AI is affecting many fields of business and industry.simulation n. 模拟，仿真Algorithm A second important term is “algorithm.” (Q2) An algorithm is important to all computer operations. It is a series of steps or instructions followed by a computer program to get a result. Algorithms can give rules for an AI’s behavior, helping it to realize the objectives of computer program developers. Unlike a simple computer program, AI algorithms permit a computer system to “learn” for itself.algorithm n. 算法，运算法则Machine learning A third important term is “machine learning.” Machine learning is one method that researchers have used in their efforts to produce artificial intelligence. Machine learning lets computers learn from data without being directly programmed on what results to produce. In recent years, the field of neural networks has given important results. In a neural network, connections between some nodes are strengthened and others weakened as the system learns and makes changes. Learning can be “supervised.” This means the system learns to put new data into specific groups based on a model. For example, the system could learn to identify spam in an email or other messaging programs. “Unsupervised” learning permits the system to independently discover new areas or ways of doing things. These discoveries in the available data might not have been immediately clear. An example would be letting an online store identify buying trends in sales data. (Q3) “Reinforcement” learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. One example might be a self-driving vehicle whose objective is to reach its destination as quickly as possible but also safely. That requirement would lead it to learn to stop at red lights although it requires additional time.neural adj. 神经的node n. 节点spam n. 垃圾邮件Deep learning (Q4) Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. Geoffrey Hinton received the 2024 Nobel Prize in Physics. Hinton is credited with developing deep learning. Hinton received the prize along with 1980s neural-network developer John Hopfield. Francis Bach, head of France’s SIERRA statistical learning laboratory, said this about deep learning: “The more layers you have, the more complex behavior can become, and the more complex the behavior can be, the easier it is to learn a desired behavior efficiently.” The method might help lead to scientific discoveries.Language models We now turn to large language models (LLMs). These might be the most popular example of generative AI. Large language models’ power tools like OpenAI’s ChatGPT or Google’s Gemini. Such systems are able to write long papers, answer legal questions or even produce a cake recipe based on their statistical models. But the technology is still new. (Q5) LLMs can suffer from “hallucinations” — the creation of content that is false or incorrect.hallucination n. 幻觉，虚构内容Artificial general intelligence A final important term is artificial general intelligence (AGI) — one the big goals of the whole AI field. (Q6) AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. People who push the idea include OpenAI chief Sam Altman and his competitors at Anthropic. They consider such a system to be within reach. The goal is to use large amounts of data and processing power to train LLMs that are increasingly powerful. But critics say that LLM technology has important limits, including its ability to reason. Maxime Amblard, computing professor at France’s University of Lorraine, told AFP last year, “LLMs do not work like human beings.” Amblard added that humans, as flesh-and-blood intelligent beings, are “sense-making machines” with different abilities from today’s computer systems.Part III. KEYQ1. C. 细节题。题目出处：AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. 意为：AI的主要特性是接收大量数据并使用统计方法进行处理。因此答案为C。Q2. C. 细节题。题目出处：An algorithm is ... a series of steps or instructions followed by a computer program to get a result. 以及AI algorithms permit a computer system to “learn” for itself.意为：算法是指计算机程序为获得结果而遵循的一系列步骤或指令；人工智能算法允许计算机系统“自主学习”。因此答案为C。Q3. B. 细节题。题目出处：Reinforcement learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. 意为：强化学习添加了一个反复试验的过程；在这个过程中，系统基于其结果获得奖励，从而学习和改进。因此答案为B。Q4. A. 细节题。题目出处：Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. 意为：深度学习因其使用多层神经网络而得名；原始数据依次通过每一层进行更高层次的抽象分析。 因此答案为A。Q5. D. 细节题。题目出处：LLMs can suffer from ‘hallucinations’ — the creation of content that is false or incorrect. 意为：LLM可能会出现‘幻觉’——即生成虚假或错误内容。因此答案为D。Q6. A. 细节题。题目出处：AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. 意为：AGI表达了这样一个尚未实现的梦想——机器能够再现所有人类的思维过程。因此答案为A。 （本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTUse Habit Stacking to Help Get HealthyA woman in Portland, Oregon started her daily exercise habit with one activity — walking her dog. Lindsay Kee then added movements to this daily activity. (Q1) Before leaving on the walk, she did some standing stretches. On her return, she did other exercises such as jumping jacks.jumping jacks 开合跳Over time, Kee added more exercises around the dog walk. She said adding exercises to an existing activity took the pressure off of creating a whole new daily exercise. And now more than a year later, she consistently exercises around the dog walk.Kee said, “I’ve found it to be really effective in helping me be consistent with things that I really want to do.”What Kee did is called habit stacking. Writer S.J. Scott created this term for his 2014 book of the same name. (Q2) The idea behind habit stacking is to attach something you want to start doing to something you already do every day.habit stacking 习惯叠加A common example is flossing your teeth after brushing them. However, you can use habit stacking in many areas of your daily life. Kee, for example, places her vitamins next to the coffee machine. This helps her remember to take them every morning.Exercise experts say habit stacking is especially helpful if you are trying to increase exercise time.Dana Santas is a movement expert who has trained more than 50 professional sports teams. She combines exercise habits with personal health care. (Q3) For example, Santas does push-ups before every shower. And she does leg exercises while brushing her teeth. She says that her electric toothbrush makes a sound every 30 seconds to remind her to brush different teeth. But she uses the reminder to change her exercises. “It’s perfect,” she added.push-up n. 俯卧撑Two minutes of exercise may not get you in shape. But experts say, every little bit helps. (Q4) Experts at the U.S. Centers for Disease Control and Prevention suggest getting 150 minutes of moderate activity, like a fast walk, every week. Or you could also get 75 minutes of very energetic activity, like jogging, every week. The health experts also suggest two days a week of strength training.moderate adj. 适度的，中等强度的Most people find keeping new habits difficult. And while habit stacking is not a perfect solution, it does help with one barrier — decision-making.Gretchen Rubin is the writer of Better Than Before: Mastering the Habits of Our Everyday Lives. She said habit stacking is one of the best ways to start and keep new habits. The technique helps to remove the barrier of deciding when or if to do something.Rubin shared a story of her college days. To help her stay active, she would only shower if she had exercised that day.She suggested combining the new, or what she calls “shaky” behavior with something you have to do or deeply want to do.(Q5) “So you have to do the shaky habit before you get to the strong habit,” Rubin said. (Q5) If she wants to listen to a podcast, her strong habit, she must do it while exercising on a running machine. For her, this will strengthen her shaky habit.Part III. KEYQ1. B. 细节题。题目出处为：Before leaving on the walk, she did some standing stretches. 意为：在开始遛狗前，她会做一些站立伸展运动。这表明Kee最初通过在遛狗前做站立伸展运动来培养锻炼的习惯。因此答案是B。Q2. C. 主旨题。题目出处为：The idea behind habit stacking is to attach something you want to start doing to something you already do every day. 意为：习惯叠加背后的理念在于，将你想要开始做的事与你每天已经在做的事联系起来。因此答案是C。Q3.

To preserve traditional writing styles.B. To improve students’ artistic abilities.C. To enhance brain development and related skills.D. To ensure compliance with federal education standards.Part II. TRANSCRIPTHandwriting Returns in California Schools(Q1) Starting this year, six-to-twelve-year olds in California will be required to learn cursive handwriting. The return to handwriting comes after many years in which typing on computer keyboards was taught and handwriting was pushed aside. Cursive is a kind of handwriting in which all the letters in a word are connected to each other. cursive handwriting 英文花体Assembly Bill 446 requires that handwriting be taught to 2.6 million Californian students in grades one through six. And it requires cursive lessons in grades three and above. (Q2) Former elementary school teacher Sharon Quirk-Silva supported the bill and California Governor Gavin Newsom signed it into law in October.(Q5) Experts say learning cursive improves brain development, reading skills, and hand movement. Some educators also find value in teaching children to read historic documents and family letters from past generations.Pamela Keller teaches grades four to six at Orangethorpe Elementary School in Fullerton about 50 kilometers southeast of Los Angeles. She said she was already teaching cursive before the law took effect on January 1. (Q3) Some children complain about the difficulty, but Keller has a ready answer: “We tell them, well, it’s going to make you smarter, it’s going to make some connections in your brain, and it’s going to help you move to the next level. And then they get excited because students want to be smarter. They want to learn,” Keller said.(Q4) During a recent visit to the school library, Keller said one student got excited seeing an image of the U.S. Constitution, written in 1787, saying, “It’s cursive!” Several of Keller’s students say the subject was difficult, like the letter Z, but they enjoyed it anyways.“I love it, because I just feel it’s fancier to write, and it’s fun to learn new letters,” said Sophie Guardia, a 9-year-old in the fourth grade. In teacher Nancy Karcher’s class, her third-grade students said, “It’s fun,” “Now I can read my mom’s writing,” and “It’s for my secrets.”As computers and smart devices grew in popularity, cursive writing was pushed aside. In 2010, the national Common Core education standards were published to help students prepare for university. Cursive was left out. “They stopped teaching kids how to form any letters at all. Teacher colleges are not preparing teachers to teach handwriting,” said Kathleen Wright. She is the founder of the Handwriting Collective, a nonprofit group.But cursive is coming back. California became the 22nd U.S. state to require cursive handwriting and the 14th to pass a cursive teaching bill since 2014, said Lauren Gendill. She is a researcher at the National Conference of State Legislatures. Five states have introduced cursive bills so far in 2024.legislature n. 立法机关Leslie Zoroya is project director for reading language arts at the Los Angeles County Office of Education. (Q5) She said research has shown that learning cursive supports several linked skills that improve childhood development. Zoroya said, “You’re using different neural networks when you’re doing cursive rather than printing. And so, it’s creating those pathways in your brain.”neural adj. 神经的；神经系统的Zoroya said she got the idea from former California Governor Jerry Brown. California’s teaching standards always had cursive writing goals, but Quirk-Silva said cursive was not always taught and was weakening. She said, “The hope of the legislation is that by the time students leave sixth grade, they would be able to read and write it.”Part III. KEYQ1. B. 细节题。文本提到：“Starting this year, six-to-twelve-year olds in California will be required to learn cursive handwriting.” 意为：“从今年开始，加利福尼亚州六到十二岁的孩子们将被要求学习花体字书写。” 因此答案为B。Q2. D. 细节题。文章中提到：“Former elementary school teacher Sharon Quirk-Silva supported the bill and California Governor Gavin Newsom signed it into law in October.” 意为：“前小学教师Sharon Quirk-Silva支持该提案，加州州长Gavin Newsom在十月将其签署成法。” 因此答案为D。Q3. B. 细节题。文本提到：“Some children complain about the difficulty, but Keller has a ready answer: ‘We tell them, well, it’s going to make you smarter...’” 意为：“一些孩子抱怨这很困难，但Keller有准备好的回答：‘我们告诉他们，好吧，这将使你更聪明……’” 因此，可知Keller认为教授花体字书写虽然具有挑战性，但对学生有益。因此答案为B。Q4. A. 推理题。文本描述了“During a recent visit to the school library, Keller said one student got excited seeing an image of the U.S. Constitution, written in 1787, saying, ‘It’s cursive!’”，即在学校图书馆参观期间，一个学生看到美国宪法的花体字书写时兴奋地说：“这是花体字书写！”， 这反映了学生因为能够识别并理解花体字而感到成就和认可。因此答案为A。Q5. C. 主旨题。文本中提到“Experts say learning cursive improves brain development, reading skills, and hand movement.”以及“She said research has shown that learning cursive supports several linked skills that improve childhood development”，意为：“专家表示，学习花体字书写有助于促进大脑发育、提升阅读技能以及手部运动能力。”和“她说，研究表明学习花体字书写有助于培养多种相关技能，从而促进儿童成长。” 也就是说，重新引入花体字书写是为了促进大脑发展和相关技能。因此答案为C。（本文图片来源于摄图网，版权归摄图网所有)

What is the primary feature of the car “fob” mentioned in the text?A. It has a long-range communication capability.B. It can unlock the car door as the owner approaches.C. It requires manual activation to send a signal.D. It can only be used within a few feet of the car.Q2. What is a potential vulnerability of the fob that thieves could exploit?A. The fob can be easily damaged.B. The signal from the fob can be cloned by thieves.C. The fob is too expensive for most car owners.D. The fob’s signal can only be sent when the car is unlocked.Q3. What does Steve Launchbury recommend to protect the car key’s signal?A. Storing the key in a Faraday bag.B. Keeping the key in the microwave or freezer.C. Frequently reprogramming the key.D. Using the car's touchscreen to secure the signal.Q4. What is one of the traditional methods to deter car theft that is still considered effective?A. Using a steering wheel lock.B. Hiding the key in the car.C. Painting the car to make it less noticeable.D. Disabling the car’s alarm system.Q5. What is a new theft technique that involves the car’s controller area network (CAN)?A. Jamming the CAN to prevent communication between car parts.B. Physically connecting to the CAN to send unlock or start signals.C. Using a Faraday bag to block the CAN’s signal.D. Cloning the CAN’s signal with a scanner.Part II. TRANSCRIPTHow to Protect Your Car from Being StolenMost recent cars have an electronic key that lets the owner get into and start the car.The electronic key is called a “fob” to those who know about the technology. (Q1) The fob sends a short-range signal to the car. As the owner gets close, the fob unlocks the door.(Q2) But the new technology also makes it easier for criminals to open the car without the key.When you lock your car and take the key with you inside your home, the fob does not stop sending its signal.Thieves, who have special equipment known as scanners, will pass by streets with a lot of cars. (Q2) If the scanner shows that a fob is sending a signal, the thieves use a device that clones the signal and opens the car doors.Government officials around the world have asked carmakers to warn car buyers of the risks of the new technology. They also have asked them to make the fobs more secure.Until then, what can you do to prevent your car from being stolen?Steve Launchbury has some suggestions he shared with the Associated Press. He is the head engineer of automotive security company Thatcham Research based in Britain. Place your key in a protective bag“It’s relatively easy for drivers to protect themselves,” he said.(Q3) The first tip is to put your key into a protective container or bag when you get home. One kind is called a Faraday bag. They are not very costly. The bag is made from a special metal material called mesh that blocks the signal from the fob. Just do not forget to put any extra keys you have into that bag, too.Some advice that is easy to find online says people should put their keys into the microwave or freezer to prevent their signal from being stolen. Launchbury said that does not work and it could harm your key.Get a steering wheel lock(Q4) You may have seen large locks that go across the steering wheel in television advertisements many years ago. It turns out they are still useful. They may be considered “old school,” but the presence of big locks that are easy to see makes car thieves turn away. The only problem is that you must take extra time to unlock the device and put it away before you can drive away.steering n.（车辆等的）转向装置Change the settingsSome car makers permit owners to deactivate the signal sent out by the fob. For Ford, Honda and Audi, owners can use their car’s touchscreen system to find the correct way to turn off the signal. For Toyota, you can turn off the signal by pressing a combination of buttons on the fob.Read your car’s owner’s manual to be sure how to do this.Some car makers include motion sensors on their key fobs. If the fob has not been moved in a while, the fob turns off.If you buy a used car, some experts suggest that you get your keys reprogrammed in case the earlier owner still has a key.New theft techniquesLaunchbury said some cars have a new system called a controller area network, or CAN. The network permits different parts, or components, of the car to communicate with each other. (Q5) He said some thieves are trying to join the CAN through some physical electronic connection to unlock the car. They can do this by removing a headlight and plugging in a device that lets them in the car’s network.The device can send a signal, such as “unlock” or “start” to the central system.Launchbury said this is where the physical lock can cause thieves to change their mind and force them to move on. Owners can also consider electronic immobilizers. These devices prevent a car from moving even if a thief gets into the internal system. However, immobilizers can be costly.Part III. KEYQ1. B. 细节题。根据：“The fob sends a short-range signal to the car. As the owner gets close, the fob unlocks the door.”意为：“fob向汽车发送短距离信号。当车主靠近时，fob会解锁车门。”这表明fob的主要特点是能够在车主靠近时自动解锁车门，答案为B。Q2. B. 细节题。根据：“If the scanner shows that a fob is sending a signal, the thieves use a device that clones the signal and opens the car doors.” 意为：“如果扫描器显示fob正在发送信号，小偷们会使用一种设备克隆信号并打开车门。” 这表明fob的一个潜在漏洞是其信号能被小偷克隆，答案为B。Q3. A. 细节题。根据：“The first tip is to put your key into a protective container or bag when you get home. One kind is called a Faraday bag.” 意为：“第一个建议是，当你回家后，把你的钥匙放入一个保护性的容器或袋子里。其中一种叫做法拉第袋。” 这表明Steve Launchbury推荐将钥匙放在法拉第袋中来保护汽车钥匙的信号，答案为A。Q4. A. 细节题。根据：“You may have seen large locks that go across the steering wheel in television advertisements many years ago. It turns out they are still useful.” 意为：“你可能在多年前的电视广告中看到过横跨方向盘的大型锁。事实证明，它们仍然有用。”这表明使用方向盘锁是一种传统的且仍然有效的阻止汽车被盗的方法，答案为A。Q5. B. 推理题。根据：“He said some thieves are trying to join the CAN through some physical electronic connection to unlock the car. The device can send a signal, such as ‘unlock’ or ‘start’ to the central system.”意为：“他说一些小偷正试图通过某种物理电子连接加入CAN以解锁汽车。该设备可以发送一个信号，例如‘解锁’或‘启动’到中央系统。” 这可以推断出一种新的盗窃技术涉及物理连接到CAN以发送解锁或启动信号，答案为B。（本文图片来源于摄图网，版权归摄图网所有)

The main focus should be on rehabilitation and improving quality of life.C. The primary challenge is developing a specific medical treatment for Long COVID.D. The most important aspect is to conduct more clinical trials for new treatments.Part II. TRANSCRIPTWHO’s Science in 5: What Is Long COVID?Vismita Gupta-Smith: If you have recovered from COVID but still have some symptoms, could that be Long COVID? How long do these symptoms last? Is there treatment available? Here to talk about Long COVID today is Dr. Jamie Rylance. Welcome, Jamie. Jamie, talk to us about Long COVID. How does it affect people?Dr. Jamie Rylance: Yeah. Thanks, Vismita, pleasure to be here. So Long COVID can happen to anybody after their acute illness. It can come on as a continuation of symptoms or new symptoms and it can last a long time. The problem is, the symptoms are very variable. Patients may have difficulty recognizing that they have it and healthcare workers, to be honest, can also struggle to identify it. (Q1) But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath. Those are the main symptoms, but there are so many others. One of the problems is that those symptoms can also represent other medical illnesses. So it’s really important to get the diagnosis right and healthcare workers and patients need to work together to do that. So when scientists have looked for what are the underlying causes of Long COVID, there’s many different abnormalities that have been seen. (Q2) Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us. And that being so many different possibilities, there’s no single one diagnostic test. That said, we need to get patients onto treatment. We focus on the things that are bothering them, the symptoms, and making sure their function comes back to normal.diagnosis n. 诊断；（问题原因的）判断blood clot 血凝块；血块Vismita Gupta-Smith: Jamie, do people experience Long COVID differently? Are symptoms different and why? Dr. Jamie Rylance: Well, the obvious thing is no two people are the same and it can be very different. That said, we do know some things that might predict whether you’re more at risk of having Long COVID or for how long the symptoms might last for.Vismita Gupta-Smith: Jamie, talk to us about vaccination.Dr. Jamie Rylance: (Q3) So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID. At the other end of the spectrum, people who’ve had particularly severe disease are more likely to have Long COVID and the symptoms are likely to last longer. And that’s people who have been admitted to hospital or particularly to Intensive Care Unit. But we know that, the health of people before COVID is really important as well. So long-standing or pre-existing health problems. Respiratory disease, mental health problems but many others can increase the risk that you suffer long COVID. And therefore, it’s really important to try and keep and maintain a healthy lifestyle as much as possible. (Q4) So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID. And the way people access their healthcare will vary around the world. Sometimes there may be specialty services for COVID, sometimes there may be specialist doctors. But very frequently, and particularly where resources are limited, there are not. And so it’s really important that we empower primary healthcare providers to give patient centred care close to home. And that’s what we’re doing at WHO, making guidance to help healthcare workers deliver high-quality care and the education materials to support them to do so.respiratory adj. 呼吸的Vismita Gupta-Smith: So Jamie, how long do the symptoms last and even though we don’t have a pill, per se, how can we help people who are suffering from Long COVID? Dr. Jamie Rylance: Well, the first thing is that most people recover fully and that can take months and of course some people we know are badly affected for years. Although there isn’t a specific medical treatment, what we really need to do is access and treat patients for the problems that they have. Often that’s associated with rehabilitation, getting people back to functional status to enjoy life and health. There are specific medical treatments for some people and overall, that goes a long way to helping increase quality of life. So I’m optimistic in the science delivering more treatments and that’s hundreds of clinical trials going on at present. And I’d encourage people to get involved where they feel able and where they’re offered. So there’s hope, I think, in terms of new treatments. (Q5) But apart from the medical treatment, I think the biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized. They’re told that their brain fog or other symptoms are not real, and that’s demoralizing. So what they need is kindness and support through their treatment. And that comes from their family, their friends, their employers, because it’s in everyone’s best interest that people with Long COVID don’t feel alone and feel that they’re supported throughout their recovery. demoralizing adj. 使丧失信心的，令人泄气的Vismita Gupta-Smith: Thank you, Jamie. That was Science in 5 today. Until next time then, stay safe, stay health and stick with science.Part III. KEYQ1. B. 细节题。根据文本中的描述：“But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath.”可知，典型的长新冠患者可能会经历疲劳、脑雾、难以集中注意力、睡眠困难和呼吸急促等症状。因此答案为B。Q2. D. 细节题。文本中提到：“there’s no single one diagnostic test.” 以及 “Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us.” 这表明长新冠没有单一的诊断测试，造成它的的潜在原因多种多样，包括许多不同的异常情况，如微小的血凝块、免疫细胞反应改变、神经系统的异常触发或反应以及体内微生物群的变化等。因此答案为D。Q3. C. 细节题。根据文本中的信息：“So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID." 可知，疫苗接种有助于预防重症COVID疾病和长新冠。因此答案为C。Q4. B. 推理题。文本中提到：“So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID”这表明长新冠是一个全球性问题，可以影响世界上任何人，需要基层医疗保健专业人员能够识别、评估和治疗长新冠患者。答案为B。Q5. A. 主旨题。在讨论长新冠的挑战和所需支持时，Dr. Rylance提到：“The biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized.”以及 “what they need is kindness and support through their treatment.” 这表明，长新冠患者面临的主要挑战是他们的疾病没有得到认可，他们需要的是在治疗过程中的善意和支持。因此答案为A。（本文图片来源于摄图网，版权归摄图网所有)

第12届教学大赛商务英语组二等奖贺静授课

授课点评：贺静老师授课效果较好，教学目标清楚、教学方法得当、教学程序井井有条。此外，贺静老师口齿清晰，语音语调比较纯正、流利；教态端庄自然，有亲和力，教学过程中与学生互动良好，体现了以学生为主体，教师为主导的教学原则。授课分两部分。第一部分介绍该单元（Empire of Wealth）的总教学安排，用了3分30秒，时间把握得比较好。另外，设计的PPT形式多样，各种图表清楚展现了教学安排。授课开始的第三分钟，PPT显示的该单元总教学目标及三篇课文的教学目标一览无遗，加上贺静老师的阐释，清晰地传递了教学目标和学习目标，这能帮助学生在课堂内外围绕主题有效学习。紧接着，贺静老师借助PPT上的流程图比较详细地介绍了授课课文In Praise of Competitive Urges的教学安排，其中的Problem-centred教学方法对学生发现、分析和解决问题有很大帮助。之后进入第二部分：比赛授课阶段。第二部分具体授课含四个阶段。进入第一阶段Warm-up时，贺静老师显得有点紧张，但很快就调整好了状态。该阶段有教师对课文理解的提问，请学生从课文中找到相关的依据回答问题，这种做法本来值得称道，因为授课不能离开课文。但是，Warm-up阶段是课前准备阶段，因此，贺静老师在Warm-up阶段讲解课文不妥，建议把重点放在教材中的Warm-up Activities上，适当设计一些附加的活动，才符合教学逻辑。此外，在总时间为20分钟且第一阶段用了3分30秒的情况下，Warm-up阶段用了5分1秒显得有点过长。之后是第二阶段Questionnaire Results，贺静老师分析解释了调查表中的信息，谈了自己对问题的看法，期间激励学生思考、回答问题，这对培养学生的独立思考能力及理解课文非常有益。Questionnaire之后进入授课第三阶段：Wealth-flaunting Motivations / Summarizing。炫富动机是课文包含的核心内容之一。因此，讨论炫富动机有助于学生理解课文。教师要求学生从PPT上（视频13'）显示的课文段落寻找答案，并要求学生做pair work找到有关的词汇。另外，通过分析课文的修辞寓意，贺静老师阐释了文章作者的真实目的。这一点做得很好。另一方面，根据该单元内容，所授的是“综合商务英语”课程。因此，贺静老师应更多围绕语言难点、篇章结构、写作风格、文法修辞等方面进行解释，让学生对课文有更深层次的理解。第四阶段Assignment在视频18'15"开始。课后作业包括questionnaire设计、调研报告写作、相关阅读作业。这样较好兼顾了综合商务英语课程语言学习和商务实践的教学特点。建议更多以教材内容教学为主，重视语言、篇章教学，在帮助学生充分理解课文的前提下掌握一些商务知识和技能；需要结合课文融入更多的思政教育内容。点评专家：翁凤翔
